Drop old integer-gmp-0.5 from GHC source tree

This completes what c774b28f76ee4c220f7c1c9fd81585e0e3af0e8a (#9281)
started.  `integer-gmp-1.0` was added as an additional
`libraries/integer-gmp2` folder while retaining the ability to configure
GHC w/ the old `integer-gmp-0.5` to have a way back, and or the ability
to easily switch between old/new `integer-gmp` for benchmark/debugging
purposes.

This commit removes the old `libraries/integer-gmp` folder and moves
`libraries/integer-gmp2` into its place, while removing any mentions of
"gmp2" as well as the to support two different `integer-gmp` packages in
GHC's source-tree.

-description:
-    This package provides the low-level implementation of the standard
-    'Integer' type based on the
-    <http://gmplib.org/ GNU Multiple Precision Arithmetic Library (GMP)>.
-    .
-    This package provides access to the internal representation of
-    'Integer' as well as primitive operations with no proper error
-    handling, and should only be used directly with the utmost care.
-    .
-    For more details about the design of @integer-gmp@, see
